STOP-MOTION FOR LOOMS.

Specification of Letters Patent.

Patented April 28, 1908.

Application led February 27, 1906. Serial No. 303,212.

To all whom it may concern:

Be it known that I, FELIX ODONNELL, a citizen of the United States,residing at the city of Pawtucket, in the county of Providence and Stateof Rhode Island, have invented certain new and useful ImprovementsinStop-Hotions for Looms, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to stop motions for weft replenishing looms, andhas for its object to produce a simple and effective stop motion thatkmay be attached to the weft replenishing mechanism and one that may beset so as to stop the loom automaticallyT when the last cop has beendischarged from the cop carrying wheel, or when said wheel arrives atany predetermined position in the course of a revolution.

This invention is an improvement on the mechanism for this purposeillustratedand described in my United States patent issued July 25,1905, No. 795,364. A

The invention is fully set forth in this specification and moreparticularly pointed out in the appended claims.

In the accompanying drawings: Figure 1- is a side elevation of part ofthe loom and replenishing mechanism illustrating the stop mechanismattached to the cop carrying wheel. Fig. 2- is a skeleton view inperspective illustrating the actuating arm and the mechanism throughwhich the stopping lever is released and thrown off whenthe actuatingarm is raised. Fig. 3- is a central longitudinal section showing thetripping device connected to the outer end of the shaft on which ismounted the cop carrying wheel. Fig. 4- is a sectional end view of theratchet on line 4*-4 of Fig. 3, showing the spring actuated pawllengaging the teeth in the hub. Fig. 5- is an end View of the hub and itsadjusting ring showing the indicating figures on the flange of said hub,by which figures the ring may be set to stop the loom at anypredetermined position.

Referring to the drawings, at 1 1 are the end frames of the loom, and 2is a portion of the loom arch which is supported from said frames.

3 is the breast beam connecting the two end frames together.`

At 4 is the frame work on which is mounted the weft replenishingmechanism. At 5 is the shaft journaled at 6 in said frame to which shaftis fixed the cop carrying wheel 7 on one side of the bearing, and theadjustable tripping stop mechanism on the opposite side of the saidbearing. This tripping device is constructed of a flanged hub 9 keyed tothe shaft 5, the periphery of this hub is cut with ratchet teeth 10, thenumber of these teeth corresponding with the number of cop holders 11 onthe cop carrying wheel 7, and these teeth are lined off and numbered onthev face of the flange 14, see Fig. 5. Mounted on this hub is theadjustable ring 12 in which is held the spring actuated pawl 13 thatengages the teeth of the hub. This pawl works in a hole 15 in the ring,and is pressed downward by the spring 16 which spring is held inposition by the screw plug 17. Near one edge of this ring is an annulargroove 18 to receive and guide the actuating arm 19. This armis pivotedat 2O to the frame and extends forward over the collar and a shortdistance in front of the same. As a matter of convenience the arm iscurved at 21 to conform somewhat to the circular groove 18 in thecollar. Projecting downward from the underside of this arm is the tooth22 the edge of which rides on the bottom of the groove in the collar andserves to support the free end of the actuating arm 19. The engagingface of this tooth 22 is beveled back at 23 (see Fig. 2) so that thetripping pin 24, that is set across the said groove for this purpose,may ride under the said beveled face of the tooth and raise saidactuating'arm in the course of the revolution of the collar. The freeend of this actuating lever is connected to the rocker shaft 25 throughthe connecting rod 26 and lever 27 and when said actuating arm is raisedthe shaft 25 is rotated and the arm 30 is caused to engage the knock-olflever 28 and actuate the same to throw the stop lever 29 out ofengagement with its usual retaining notch, allowing the same to springback and stop the loom. Often times it is found convenient and desirableto connect other sto motions to this rocker shaft 25, which sha t isplaced beneath the breast beam 3, it is therefore necessary thatconnections to said shaft should be so arranged that each sto motionrconnected thereto should worr entirely independent of the other. Toaccomplish this I have provided an elongated hole 31 in the arm 27through which the connection 26 passes, thereby allowing said copcarrying mechanism and is not confined to any particular type.

The operation of the mechanism is further described as follows: Therotary cop carrying wheel to which my device is attached is of thewell-known type and it may be constructed and operated in any desiredmanner.

It has heretofore been found necessary for the o erator of this class oflooms to constantfy watch the same when in operation so as to stop itwhen the last cop has been transferred from the carrier wheel to theshuttle' in order to prevent the transferring mechanism from operatingat each stroke of the loom, thus preventing racking or unnecessary wearand tear on the transferringv mechanism. My device is of a very simpleconstruction which may be connected in any convenient manner to therotating cop carrying wheel. It may be connected to the wheel and set tostop the loom at any predetermined point, or at the transferring of anyparticular cop, it usually being set however, to stop the loom after thelast cop has been transferred into the shuttle.

To simplify the setting of the tripping mechanism l have numbered eachcop retained on the wheel, as shown in Fig. 1, and T have also numberedthe ratchet teeth in the hub, the numbers appearing on the face of thehub at 14, as shown in Figs. 1 and 5. The number of said ratchet teethmust correspond exactly with the number of cop holders on the wheel. Inorder to set the device so that it will operate at the positioning ofany given cop, the ring 12 that carries the spring pressed pawl 13 andalso the tripping pin 24, is turned around by hand on the hub until theindicating mark opposite the said pin registers with the number of thecop carrier at which the loom is to be stopped. For instance, if it isdesired to stop the loom after cop No. 10 -has been transferred into theshuttle, the collar 12 is rotated on the hub until the said indicatingmark registers with number 10 on the flange 14, the pawl 13 will thenengage the necessary tooth in the hub and retain the ring in this setposition to rotate with the cop carrying wheel. Then as the said wheelturns step by step as one cop after another is transferred therefrominto the shuttle, this tripping pin 24 finally reaches the positionshown in Fig. 2, where it comes in contact with the inclined face of thetooth on the actuating arm 19, riding under the same and raising saidarm which, through the mechanism described above, throws 0H the stoppinglever and the loom is instantly and automatically stopped.

This mechanism is extremely simple and practical in construction, easilyattached to the loom and obviates the necessity of constant watchfulnesson the part of the attendant thereby enabling him to operate moremachines and eifectually prevents unnecessary wear and 'tear of the weftreplenishing mechanism.

Having thus described my invention, what I claim as new and desire tosecure byLetters Patent, is:

1. In a device of the character described, a stop lever, rotary meansfor carrying cops to be transferred into a shuttle, actuating meansrotated by said cop carrying means, means engaging said actuating means,and a connection between said engaging means and said stop lever wherebythe latter is knocked off to stop the loom at a predetermined point inthe rotation of the cop carrier.-

2: In a device of the character described, rotary means for carryingcops to be transferred into a shuttle, actuating means rotated by saidcop carrier, a lever engaging said actuating means, a rock shaft and apositive connection between said lever and said shaft whereby the loomwill be automatically stopped at a predetermined position of saidcarrier.

3. In a device of the character described, o
